I love this hairstyle. It's another that would be perfect for Valentine's Day. Set aside lots of time for this one (it took me 45 minutes): Part out a heart shape around the back of her head and put that hair into a rubber band to hold it out of the way. Part out another heart (using the first as a "template") around the first heart. French braid each side of the larger heart (taking hair from only one side to keep the braid in a heart shape), then do the same to the smaller heart. Gather all hair at the bottom of the two hearts and finish with a messy bun or - as I did - with a bunch of little braids. A1 thought she was so pretty with these hearts.
